The v-for directive in vue is truly remarkable.
I am currently faced with a situation where I need to create a description list similar to this. To achieve this, I have to generate two DOM elements for each item in my array:
<dl class="row">
<dt class="col-sm-3">Description lists</dt>
<dd class="col-sm-9">A description list is ideal for defining terms.</dd>
Is there a more elegant way to accomplish this using vue?
If you want to display a block of multiple elements using Vue.js, you can utilize the <template> tag along with the v-for directive.
new Vue({
el: "#app",
data() {
return {
items: [
{ short: "1", long: "Long Description 1" },
{ short: "2", long: "Long Description 2" },
{ short: "3", long: "Long Description 3" },
{ short: "4", long: "Long Description 4" },
]
}
}
})<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" rel="stylesheet"/>
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<div id="app">
<dl class="row">
<template v-for="data in items">
<dt class="col-sm-3">{{data.short}}</dt>
<dd class="col-sm-9">{{data.long}}</dd>
</template>
</dl>
</div>In accordance with the MDN, the HTML5 specification permits enclosing <dt> and <dd> elements within a <div> for microdata or styling purposes. Here is a suggested approach:
<dl class="row">
<div v-for="item in items" :key="item.id">
<dt class="col-sm-3">{{ item.key }}</dt>
<dd class="col-sm-9">{{ item.value }}</dd>
</div>
</dl>
This method also takes care of the requirement for a :key attribute when using v-for.
If you want to avoid using a wrapping element when rendering content in your HTML, you can utilize
<template v-for="item in items"></template>For example:
<template v-for="item in items">
<dl class="row">
<dt class="col-sm-3">Description lists</dt>
<dd class="col-sm-9">A description list is perfect for defining terms.</dd>
</dl>
<dl class="row">
<dt class="col-sm-3">Description lists</dt>
<dd class="col-sm-9">A description list is perfect for defining terms.</dd>
</dl>
<template>
